CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 326,405, datedSeptember 15, 1885.

Application filed July 23, 1885. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM D. COOPER, of Wayne, in the county of Wayneand State of Michigan, have invented new and useful Improvements inGar-Axle Lubricators; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being bad to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in theconstruction of attachments to car-axle boxes, by means of which thejournal of the axle is kept lubricated.

The invention consists in the peculiar construction, arrangement, andcombination of the parts, all as more fully hereinafter set forth.

Figure 1 is a central vertical longitudinal section through theaxle-box, the end of the axle, and my improvement. Fig. 2 is a verticalcrosssection through the same.

In the accompanying drawings, which form a part of this specification,.A represents a car-axle box of the ordinary or standard construction.

B represents a removable oil receptacle which is designedto be insertedin the bottom of the box and rest upon the bearingsprings G and endspring, H. In this receptacle B, I journal in proper bearings, D,whichshould preferably be made removable, so that they can readily bereplaced when worn, a shaft, I, which carries a roller, 0, which ispreferably made of semi hard rubber or other suitable elastic material.This roller is journaled at the bottom of a semicircular recess or wellin the upper portion of the receptacle, the walls of which come in closeproximity to but do not touch the roller, as is clearly shown in Fig. 2.The axle arm or journal rotates within this well, and in frictionalcontact with the roller.

In practice the oil or proper lubricant is introduced to the receptaclethrough the door J. When traveling,the rolling of the axle, being, asheretofore said, in frictional contact with the roller 0, compels thelatter to turn upon its journals, and as it is submerged, or partiallysubmerged, by the lubricant, it delivers a fresh supply thereof to thejournal, which in turn supplies and lubricates the bra-sses F, whichrest upon the top of the axle, thereby keeping all the parts. which inthis class of rolling-stock frequently become heated, supplied with acontinuous lubricant.

It will be noticed that the bottom of the receptacle is slightlyconcave, so that its deep est point is immediately below the center ofthe lubricating roller. It will also be ob- 6o served that the springs Gand H are for the purpose of keeping. the receptacle in its relativeposition to the journals and a frictional contact between this rollerand the journal in the various movements that are attendant in a carunder motion.

Thelubricant-receptacle Bis formed with an inclined side, b,corresponding to the inclined side a of the outer box, A. This formthrows the filling-aperture,with its cover J, into convenient positionfor filling, while the spring H, being located between the parts a b,serves to throw the receptacle inward. These features, in connectionwith the concave form given to the box, I deem to be important.-

I am aware of thePatent No. 114,157, of 1871, and do not seek to coverthe construction therein set forth.

What I do claim is 1. The combination, with the axle-box A, havinginclined side a, of the removable oilreceptacle B b, of similar form,and having an oil-filling orifice, as shown, the springs G, supportingthe receptacle in a vertical direction, spring H, acting between thesides a b, and solid lubricating-roller 0, all adapted to serve with thejournal E as and forthe purposes set forth.

2. In an axle-box, the combination,with the box A, springs GI-Landjournal E, ofthe re- 0 ceptacle B,with its bottom formed concavein crosssection, and the solid friction-roller O, journaled in thereceptacle and lying in the trough formed by said bottom, as set forth.
